You can try below workflow:

 

1. Download the attached sample excel which defines the 3D points for creating the sweep path.

2. New a part document and create a 3D sketch.

3. On the 3D Sketch tab, call Insert->Points command.

4. With the Open dialog, choose the excel and click the Options... button to change the Import Options to Create lines.

5. Click OK and Open to create the 3D sketch lines, and then click the Bend command and select each corner point to create the bend so the sweep is smooth at the corners.

6. Exit 3D sketch, and create a 2D sketch bases on XZ plane, and create a circle with its center on origin.

7. Exit 2D sketch, and create a sweep feature with the circle as profile and the 3D sketch lines as path.

 

Hope  this helps.

Hi blmckenzi3,

 

You can do this by extruding a profile as a surface (rather than a solid).

You might use the End of Part marker in the examples at the link to examine how the features were created one at a time.

This is often a good way to learn a new technique. Post back if you have more questions and I'm sure someone will help.

 

I hope this helps.

Hi blmckenzi3,

 

You might also see JDMather's knot tutorial for more on the general technique:
